Injection Moulding
Boron Granules are defined by their high melting point, low density, and strong neutron absorption capability, alongside resistance to oxidation and chemical degradation. They are widely applied in metallurgy, ceramics, and specialty chemical production, serving as an additive or reactive medium to enhance performance properties. Specific uses include improving hardness and wear resistance in metal alloys, acting as a reactant in boride synthesis, and serving as a stabilizing component in advanced ceramic materials. In research, boron granules facilitate the development of new alloys and high-performance materials, enabling advances in fields from energy storage to high-temperature engineering. Industrially, they add value by extending product lifespans, improving mechanical performance, and enabling new material capabilities.
